Continuity mistake: Towards the beginning of the film, Hawkeye steals a jeep and drives off, splattering mud everywhere. When the local commander shouts to the MPs to "get that guy", the next shot shows them driving off onto totally dry ground; in fact, when their jeep abruptly stops, there is dust everywhere.

Continuity mistake: When the lady reporter is filming Hawkeye from her truck, she's approaching his position. After passing by him, she turns in the truck to keep him in range, filming backwards. But the movie camera angle filming Hawkeye is always approaching him, and at a slower speed than the reporter's truck was moving.

Near the end of the film, there is a football game played between the rival MASH units. Although the game is supposed to be taking place in a remote location of Korea in 1951, late model 1960's automobiles can be seen driving on a nearby highway as the game progresses. This gave away the fact that the football scenes were shot at a university in Southern California.
